Explanation:

1.

We need to form a question asking where the watch was found. The structure in Spanish for asking "Where did you find your watch?" is "¿Dónde lo encontraste (tu reloj)?" (using the direct object pronoun "lo" for masculine singular "reloj").

To ask where the shirt was ironed, the structure is "¿Dónde la planchaste (la camisa)?" with "la" for feminine singular "camisa".

For the plural feminine "las gorras", we use "las" and ask "¿Dónde las guardaste (las gorras)?" to know where they were stored.

Answer:

¿Dónde lo encontraste (tu reloj)?
